背景:成人和儿童创伤性脑损伤 (TBI) 的治疗和护理是一个棘手的全球健康问题。预测 TBI 患者的预后和住院时间可能会改善治疗效果并显著减轻社会医疗负担。将新型机器学习方法应用于 TBI 领域可能对确定临床治疗的预后和成本效益很有价值。目的:我们旨在结合多种机器学习方法来构建混合模型,用于预测成人和儿童 TBI 的预后和住院时间。方法:我们收集了 2017 年 5 月至 2022 年 5 月期间在安徽医科大学第二附属医院神经外科中心接受治疗的患者的相关临床信息,其中 80% 用于训练模型,20% 用于通过筛选和数据拆分进行测试。我们使用 5 次交叉验证来训练和测试机器学习模型,以避免过度拟合。在机器学习模型中,11种类型的独立变量被用作输入变量,用于评估患者预后的格拉斯哥预后量表评分和患者住院时间被用作输出变量。模型训练完成后,我们通过5轮交叉验证获得并比较每个机器学习模型的误差,以选出最佳预测模型。然后使用2021年6月至2022年2月在安徽医科大学第一附属医院接受治疗的患者的临床数据对模型进行外部测试。结果:最终的卷积神经网络-支持向量机(CNN-SVM)模型在测试集和外部验证集中预测格拉斯哥预后量表评分的准确率分别为93%和93.69%,曲线下面积在测试集和外部验证集中分别为94.68%和94.32%。最终构建的卷积神经网络-支持向量回归(CNN-SVR)模型在测试集和外部验证集中预测住院时间的平均绝对百分比误差分别为10.72%和10.44%。判定系数(R 2 )在测试集和外部验证集中分别为0.93和0.92。与单独建立的反向传播神经网络、CNN和SVM模型相比,我们的混合模型被判定为最优且具有较高的置信度。结论:本研究证明了通过结合多种机器学习方法构建的2个混合模型的临床实用性,可准确预测成人和儿童TBI的预后和住院时间。这些模型的应用可以减轻医生评估TBI时的负担,并协助临床医生进行医疗决策。
据 Schultz 介绍,他们通过 50 次工业洗涤测试了 Stay Fresh 面料。“它吸收了工业洗涤循环中使用的过氧化物,有效地补充了其抗菌活性,”他说,并在所有洗涤过程中保持无菌表面。其他非正式研究是在手术室进行的,研究对象是使用 Stay Fresh 面料制成的衣服。“我们从经过处理和未经处理的手术服中培养了细菌,”Schultz 说。“麻醉师的裤子或衬衫,尤其是如果它们溅上了血液、尿液或唾液,可能会
• 液体管理是一个促进正确管理静脉 (IV) 液体和药物的过程,目的是减少液体超负荷、改善患者预后和减少不良事件 1 • 重症监护病房 (ICU) 中的液体超负荷与死亡率增加有关,并会导致严重的并发症,例如肺水肿和心力衰竭 2 • 液体包括复苏液、维持液和“隐藏液体”,是 ICU 中最常用的处方药 1 • 隐藏液体的例子有血液制品、冲洗液和 IV 药物 1 • 文献显示,IV 药物占 ICU 入院第一天总液体摄入量的 61%,占前七天总液体摄入量的 40% 3 • 但是,对显著影响液体状态的 IV 药物进行分类的数据有限

• Small medical practices can thrive with healthcare mobile solutions like OneTalk, and thanks to intelligent routing, patients' calls can be quickly attended while doctors and nurses stay linked, whether dashing between exam rooms or on call from home • Modernizing analog phone systems (like plain old telephones (POTS) or private branch exchanges (PBXs)) with advanced wireless technology can help a growing medical practice control costs and scale operations more quickly and efficiently • A good沟通基础设施合作伙伴可以通过更少的资源
